Why does Huawei Mate30 have abnormal sounds in the body at times?

Hello, there are sometimes abnormal noises inside the Huawei Mate30, probably because Huawei uses an optical image stabilization lens. Optical image stabilization lenses have this problem. It's normal.

If there is an abnormal sound in the body, you can go to the after-sales service to check the phone.

It may be because some parts in the body are loose and need to be tightened, or the phone is damaged when it leaves the factory.

This is not usually the case.

If this happens, it may generally be a bad product.

Because Huawei mobile phones will vibrate during operation, so that there will be a sound.

Huawei doesn't have a special three-zero, and sometimes some of his physical machines have abnormal internal noises, which are all system problems. If you have more, you can go to the after-sales service to solve it.

When the phone vibrates and the sound changes, it's not that the vibration sound changes, but that the vibration frequency changes, and it may be caused by you switching to another app.
